What is the minimum amount of light required to eject electrons from its shell?

This speaks about the Photoelectric effect; when light touches an object it reflects back. Please state your answer in 0C.

It depends on the element.

If you're lucky, the minimum amount is one photon, which is little.
But there is a minimum frequency.

It depends highly on the element from which elctron is ejected.If it is a bigger atom like potassium then ejection would be easier i.e lesser amount of photons required !

@isha2ubt

You are confusing amount of energy required with amount of photons required.  Photons have different amounts of energy depending on their frequency of oscillation.
